Original application flied August 3, 1905, Serial No.` 272,597. Divided and this application filed October 30,

` 1908, Serial No. 460,319. Renewed March 12, 1915. Serial No. 13,971.

To all whom t may concern Be it known that I, FREEMAN It. VILL- soN, Jr., a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Conveyers, of which the following 'is a specification, reference being had therein` to the accompanying drawing.

My invention relates to that class of conveyers in which idler pulleys orirollers are employed for giving to a conveying-belt a trough-like form for the purpose of better retaining the material conveyed within the edges of the belt. j

The object of the invention is, to provide y' improved means for tilting the idler pulleys but more particularly means for unloading the material conveyed at any desired point.

In the drawings,-Figure 1 is a side elevation of a structure embodying my invention. Fig. 2 is a sectional view of the same taken on the line 2-2, Fig. 1.

I have shown my invention as embodied in connection with pulley-supports for a flatface conveyer. p The lower stationary frame, consisting of the base portion A, and the TJertical walls B, C, alford a guideway or .channel for the movement ofthe adjustable frame G. The

.frame G has a-web `portion g, and upper and lower flanges g', g2, and is arc-shaped in side elevation. The frame G has upwardly extending arms H, H', which afford bearings in which a shaft N is journaled, Said. 'Shaft Carrying the pulleys D, E which afford a support for' a Hat-face conveyer F, The frame G is provided with a curvilinear slot K, which extends through the greater part of the length of the frame, and is preferably 'the arc of a circle. The frame is itted and movable between thewalls B, C, as a guide way, and bears on anti-frictionrollers which are mounted in the lower part of the base frame and between the walls B, C, thereof. The axes of these rollers are arranged in a circle concentric with the said slot K: i

022 is an anti-friction roller, likewise mounted between the vertical walls B, C, and arranged to bear upon and maintain the frame G in rolling engagement with the rollers w. For this purpose the axis of the roller .'02 is preferably in a vertical plane midway between the vertical planes of the axes of the rollers fr,

A screw threaded pin L, extends through the vertical walls B, C, and the slot K, and a hand wheel M, with its elongated hub-portion lm. serves to clamp the frame in any adjusted position desired.

It will be understood that the frame G is, by reason of the rollers w and m2, adjustable only in the arc of a circle, that is to say, it is bodily adjustable, but is not capable of pivotal adjustment about a point within the slot K. To inclinethe vpulleys at an angle to the horizont-al so as to tilt the conveyer belt, the hand wheel is unloosened and the slotted frame can then be readily moved to any position desired.

This application is a division of plieation 272,597, tiled Aug. 3, 1905.

What I claim is,-

l. In a conveyer belt support, the combination of a ystationary base, a pulley carrying frame mounted to have pivotal movement relative to the said stationary base about an axis parallel to 'a supported belt, said frame of a semicircular form consisting in cross section of a web with upper and lower ianges, anti-friction rollers mounted in the base and engaging the upper and lower tianges of the pulley carrying frame, the web of said frame being provided along a portion 'of its center line-with a curvilinear slot. and means for clamping said web section tothe base portion, substantially as set forth. l 2." In a conveyer belt support, the combinationof a pulley carrying frame having an the walls, pulleys on the pins in engagement with the outer and the inner curved surfaces of the supporting bar,Y and a device for lock-- ing the carrying frame inv adjusted position.-

,90 arcuate supporting bar centered about an In testimony whereof I aiix my signature,

in presence of two witnesses.
